Concupiscence
Concupiscence (from Late Latin concupīscentia, from the Latin verb concupīscere, from con-, "with", here an intensifier, + cupere, "to desire" + -scere, a verb-forming suffix denoting beginning of a process or state) is an ardent longing, typically one that is sensual. In Christianity, particularly in Catholic and Lutheran theology, concupiscence is the tendency of humans to sin.
